I'm trying to use the user_profile_update_errors hook, however it doesn't appear to be executing.
I'm calling it like this:
add_action('user_profile_update_errors', 'blm_register_result', 10, 3);
function blm_register_result($errors, $update, $user) {
$errors->add('demo_error',__('This is a demo error, and will halt profile save'));
}
I've tried playing around with the priority parameter with no luck.
To test it all I am doing is clicking the register button and if it has any errors it will show them, but not the one I added above - if there are no errors then it will successfully register the user despite my error addition above.
Do I have to call this in a certain spot or what am I doing wrong here!?
